  • Sodium Chloride (Halite, Common Salt Or Table Salt, Rock Salt)
    71376, 71386 Sodium chloride (Halite, Common Salt or Table Salt, Rock Salt) CAS number: 7647-14-5 Product Description: Molecular formula: NaCl Appearance: white powder (crystalline) Molecular weight: 58.44 g/mol Density of large crystals: 2.17 g/ml1 Melting Point: 804°C1 Density: 1.186 g/ml (5 M in water)2 2 Solubility: 1 M in H2O, 20°C, complete, clear, colorless 2 pH: 5.0-8.0 (1 M in H2O, 25°C) Store at room temperature Sodium chloride is geologically stable. If kept dry, it will remain a free-flowing solid for years. Traces of magnesium or calcium chloride in commercial sodium chloride adsorb moisture, making it cake. The trace moisture does not harm the material chemically in any way. 71378 BioUltra 71386 BioUltra for molecular biology, 5 M Solution The products are suitable for different applications like purification, precipitation, crystallisation and other applications which require tight control of elemental content. Trace elemental analyses have been performed for all qualities. The molecular biology quality is also tested for absence of nucleases. The Certificate of Analysis provides lot-specific results. Much of the sodium chloride is mined from salts deposited from evaporation of brine of ancient oceans, or recovered from sea water by solar evaporation. Due to the presence of trace hygroscopic minerals, food-grade salt has a small amount of silicate added to prevent caking; as a result, concentrated solutions of "table salt" are usually slightly cloudy in appearance. 71376 and 71386 do not contain any anti-caking agent. Applications: Sodium chloride is a commonly used chemical found in nature and in all body tissue, and is considered an essential nutrient.

  • Chloride Ions As Integral Parts of Hydrogen Bonded Networks in Aqueous Salt Solutions: the Appearance of Solvent Separated Anion Pairs†
    Chloride ions as integral parts of hydrogen bonded networks in aqueous salt solutions: the appearance of solvent separated anion pairs† Ildikó Pethes*,a, Imre Bakób, László Pusztaia,c aWigner Research Centre for Physics, Konkoly Thege út 29-33., H-1121 Budapest, Hungary bResearch Centre for Natural Sciences, Magyar tudósok körútja 2, H-1117 Budapest, Hungary cInternational Research Organisation for Advanced Science and Technology (IROAST), Kumamoto University, 2-39-1 Kurokami, Chuo-ku, Kumamoto 860-8555, Japan Abstract Hydrogen bonding to chloride ions has been frequently discussed over the past 5 decades. Still, the possible role of such secondary intermolecular bonding interactions in hydrogen bonded networks has not been investigated in any detail. Here we consider computer models of concentrated aqueous LiCl solutions and compute usual hydrogen bond network characteristics, such as distributions of cluster sizes and of cyclic entities, both for models that take and do not take chloride ions into account. During the analysis of hydrogen bonded rings, a significant amount of ‘solvent separated anion pairs’ have been detected at high LiCl concentrations. It is demonstrated that taking halide anions into account as organic constituents of the hydrogen bonded network does make the interpretation of structural details significantly more meaningful than when considering water molecules only. Finally, we compare simulated structures generated by ‘good’ and ‘bad’ potential sets on the basis of the tools * Corresponding author: e-mail: [email protected] †Electronic supplementary information (ESI) available. See DOI: … 1 developed here, and show that this novel concept is, indeed, also helpful for distinguishing between reasonable and meaningless structural models.

  • 0.9% Sodium Chloride Injection, USP Visiv
    SODIUM CHLORIDE- sodium chloride injection, solution ICU Medical, Inc. ---------- 0.9% Sodium Chloride Injection, USP VisIV ™ Container Rx only DESCRIPTION 0.9% Sodium Chloride Injection, USP is sterile and nonpyrogenic. It is a parenteral solution containing sodium chloride in water for injection intended for intravenous administration. Each 100 mL of 0.9% Sodium Chloride Injection, USP contains 900 mg sodium chloride in water for injection. Electrolytes per 1000 mL: sodium (Na+) 154 mEq; chloride (Cl−) 154 mEq. The osmolarity is 308 mOsmol/L (calc.). The pH for the 100 mL and smaller containers is 6.0; for the 250 mL, the pH is 5.6. The pH range is 4.5 to 7.0 for all containers. This solution contains no bacteriostat, antimicrobial agent or added buffer and is intended only as a single-dose injection. When smaller doses are required, the unused portion should be discarded. 0.9% Sodium Chloride Injection, USP is a parenteral fluid and electrolyte replenisher. Sodium Chloride, USP is chemically designated NaCl, a white crystalline powder freely soluble in water. Water for Injection, USP is chemically designated H2O. The flexible plastic container is fabricated from a clear multilayer polyolefin plastic film. Exposure to temperatures above 25°C (77°F) during transport and storage will lead to minor losses in moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will lead to clinically significant changes within the expiration period. CLINICAL PHARMACOLOGY When administered intravenously, these solutions provide a source of water and electrolytes. Solutions which provide combinations of hypotonic or isotonic concentrations of sodium chloride are suitable for parenteral maintenance or replacement of water and electrolyte requirements.

  • Sodium Hypochlorite Stability
    SODIUM HYPOCHLORITE STABILITY Sodium hypochlorite is an excellent sanitiser that is commonly used in industries world-wide. Its’ popularity is derived from the fact that while it has a proven wide-spectrum of activity, it deodorises, it is non- poisonous in low concentrations and it breaks down to give harmless naturally occurring products (salt, water, oxygen). While sodium hypochlorite has many positive aspects it is a reactive compound that degrades over time. The decomposition reaction is as follows: 2 NaOCl → 2NaCl + O2 Sodium Sodium Oxygen Hypochlorite Chloride The stability and shelf life of commercially available sodium hypochlorite is adversely affected by the following factors: • Heat - For example: the shelf life of 12.5% sodium hypochlorite is decreased by a factor of approximately three times when the storage temperature is raised from 25°C to 35°C. • Low pH - Lowering the pH will decrease the sodium hypochlorite in solution, and can liberate free chlorine. • Sunlight - Exposure to UV light degrades sodium hypochlorite. • Contamination - The presence of certain metals in solution (eg nickel) will promote degradation. Some metals (e.g. iron) are not particularly detrimental to the stability. Standards Australia has recognised the stability issues associated with sodium hypochlorite. In AS1087- 1991 (“Sodium hypochlorite solutions for use in the dairying industry”, which is the most relevant standard available) the standard states: 1) “When solutions of sodium hypochlorite are allowed to stand, the amount of available chlorine slowly diminishes” and 2) “Two consequences of this decomposition are that first, the chemical properties specified must be determined, and the product delivered to the customer without undue delay; and second, the concentration of the sanitising solution must be checked before use and, if necessary, allowance made when sanitising if the solution is under-strength.” AS1087-1991 sets a few minimum requirements for stability of 12.5% sodium hypochlorite: • The initial product must have a level of 125– 135 g/L available chlorine.

  • The Water Molecule
    Seawater Chemistry: Key Ideas Water is a polar molecule with the remarkable ability to dissolve more substances than any other natural solvent. Salinity is the measure of dissolved inorganic solids in water. The most abundant ions dissolved in seawater are chloride, sodium, sulfate, and magnesium. The ocean is in steady state (approx. equilibrium). Water density is greatly affected by temperature and salinity Light and sound travel differently in water than they do in air. Oxygen and carbon dioxide are the most important dissolved gases. 1 The Water Molecule Water is a polar molecule with a positive and a negative side. 2 1 Water Molecule Asymmetry of a water molecule and distribution of electrons result in a dipole structure with the oxygen end of the molecule negatively charged and the hydrogen end of the molecule positively charged. 3 The Water Molecule Dipole structure of water molecule produces an electrostatic bond (hydrogen bond) between water molecules. Hydrogen bonds form when the positive end of one water molecule bonds to the negative end of another water molecule. 4 2 Figure 4.1 5 The Dissolving Power of Water As solid sodium chloride dissolves, the positive and negative ions are attracted to the positive and negative ends of the polar water molecules. 6 3 Formation of Hydrated Ions Water dissolves salts by surrounding the atoms in the salt crystal and neutralizing the ionic bond holding the atoms together. 7 Important Property of Water: Heat Capacity Amount of heat to raise T of 1 g by 1oC Water has high heat capacity - 1 calorie Rocks and minerals have low HC ~ 0.2 cal.

  • Chlorine What Is Chlorine?
    Chlorine What is Chlorine? Chlorine is an element found frequently in nature. By itself, it is usually found as chlorine gas (Cl2). It can also be found in a variety of common chemicals, from table salt (sodium chloride) to household bleach (sodium hypochlorite) to hydrochloric acid (hydrogen chloride). Chlorine and the closely related chloramine gas can also be accidentally formed when cleaners like ammonia and bleach are mixed together. What is chlorine used for? Chlorine has a variety of uses in industry and chemistry. It can be found in processes to make paper, solvents, insecticides, paints, medicines, plastics, and textiles. It is also used to purify water supplies and pools. Is chlorine gas harmful? At significant concentrations, yes. Chlorine gas will react with the water in human tissues to form hydrochloric acid, which is very irritating to the airways, lungs, and eyes. What are the signs of a chlorine gas exposure? Chlorine is very irritating to the throat and lungs and will cause a burning sensation with coughing and difficulty breathing. Chlorine gas can also be irritating to the eyes. Are there long term effects from chlorine gas exposures? The long term effects from a single exposure are related to the duration of the exposure and its severity. Some people will continue to experience a persistent cough and chest tightness, potentially even for years. What should I do if I think I have been exposed to chlorine gas? The most important thing you can do is to get out of the area immediately and to a safe place with fresh air.

  • Summary of Comptox Data Quaternary Ammonium Compounds
    Summary of CompTox Data Quaternary Ammonium Compounds The US EPA CompTox Chemical Dashboard1 provides access to multiple datasets, including the merged Tox21/ToxCast datasets in which >7000 chemicals have been tested in hundreds of in-vitro systems. The data can inform us about molecular pathways that may be important for further investigation. The data can also be useful to explore some endpoints that have been identified based on in-vivo analyses. It is important to recognize that there are limitations with some of the assays, the concentrations of chemicals where activity is observed. However, the composite data are useful for screening and informing – not for use as final, decision-making data. Of the Quaternary Ammonium Compounds (QACs) in commerce, a subset are High Production Volume chemicals2 and of these, a subset has been tested and reported in the EPA’s CompTox Chemical Dashboard. The CompTox data include results of testing for activity associated with nuclear receptors, a subset of which are known to be involved in the regulation of lipid and cholesterol homeostasis. We include these assay results because of the research showing/suggesting the effects of QACs on lipid and cholesterol homeostasis3,4,5. Presented in Table 1, are the biological activity data reported for QACs with interaction with nuclear receptors that are well known to be involved in regulation of lipid and cholesterol homeostasis. These include the androgen receptor (AR), estrogen receptor α (ERα) and thyroid hormone receptor β (THRβ) are most common across the tested QACs. Also included are data from interactions with glucocorticoid receptor (GR) and liver X receptor (LXR).
